Seat, seatbelt and SRS airbags/Seat heater
are located on the top of the seatback until
the head restraint locks. Press and hold
the release button to lower the head
restraint.
NOTE When the head restraint cannot be
pulled out or installed due to insuffi-
cient clearance between the head re-
straint and the roof, tilt the seat and
then perform the installation and re-
moval tasks.
! Head restraint angle adjustment
The angle of the head restraint can be
adjusted in several steps. While maintain-
ing a suitable driving posture, adjust the
head restraint to a position where the back
of your head is as close to the head
restraint as possible. To tilt:
Tilt the head restraint by hand to the
preferred position. A click will be audible
when the head restraint is locked.
To return:
Tilt the head restraint once as far forward
as it can go. The head restraint will
automatically return to the fully upright
position. Then, adjust the head restraint
again to the preferred angle. Seat heater (if equipped) The front seats are equipped with a seat
heater.
The seat heater operates when the igni-
tion switch is either in the “ ACC ” or “ ON ”
position.
CAUTION. People with delicate skin may
suffer slight burns even at low
temperatures if they use the seat
heater for a long period of time.
When using the heater, always be
sure to warn the persons con-
cerned.
. Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.
. When the vehicle ’ sinterioris
warmed enough or before you
leave the vehicle, be sure to turn
off the seat heater.
NOTE
Use of the seat heater for a long period
of time while the engine is not running1-6

you (a) do not press the trip knob for 10
seconds or (b) open and close the driver ’ s
door, the fuel gauge needle will drop to the
“ E ” position and the dial and needle will
turn off.
NOTE
. You will see the “ ” sign in the fuel
gauge.
This indicates that the fuel filler door
(lid) is located on the right side of the
vehicle.
. When you have refueled, the fuel
gauge indicates the amount in the fuel
tank after starting the engine. Also, it
may take some time until the fuel
gauge indication stabilizes.
. The gauge indicates only an approx- imate amount of fuel remaining in the
tank. Use this indication only as a
guide.
. If you refuel while the ignition switch
is in the “ ON ” position, the fuel gauge
may not indicate the correct amount of
the fuel in the fuel tank.
. If the refuel amount is less than
approximately 4.0 US gal (15 liters, 3.3
Imp gal), it may take some time until the
fuel gauge indication stabilizes.
& Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ ON ” position.
The coolant temperature will vary in accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTIONIf the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “ Engine overheating ” F 9-
11 . Instruments and controls/Meters and gauges

& Door open warning
lightThe warning light illuminates if any door or
the trunk lid is not fully closed. This
function is effective even if the ignition
switch is in the “ LOCK ” / “ OFF ” or “ ACC ”
position, or the key is removed from the
ignition switch.
Always make sure this light is not illumi-
nated before you start to drive.
& All-Wheel Drive warn-
ing light (if equipped)This light flashes if the vehicle is driven
with tires of differing diameters fitted on
the wheels or with an excessively low air
pressure in any of the tires.
WARNING
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe place then check whether
all four tires are the same diameter
and whether any of the tires has a
puncture or has lost air pressure for
some other reason. & Power steering warn-
ing light (except STI) This warning light illuminates when the
ignition switch is turned to the “ ON ”
position and turns off after the engine
has started. This indicates that the warn-
ing system is working properly.
While the engine is running, this warning
light illuminates when a malfunction has
been detected in the electric power steer-
ing system.
CAUTIONWhen the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
NOTE If the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating. . The steering wheel is operated fre-
quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
. The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too fre-
quently, that may result in a malfunc-
tion of the power steering control
system.
& LED headlight warning
light (if equipped) This light illuminates if the LED headlights
malfunction. Have your vehicle inspected
at a SUBARU dealer as soon as possible.Instruments and controls/Warning and indicator lights

appliance that can be connected
is 120W. Do not use an appliance
which exceeds the indicated wat-
tage for each outlet.
When using appliances con-
nected to two or more outlets
simultaneously, the total power
consumed by them must not
exceed 120W. Overloading the
accessory power outlet can
cause a short circuit. Do not use
double adapters or more than
one electrical appliance.
. If the plug on your electric appli-
ance is either too loose or too
tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly.
. Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause battery
discharge.
. Before driving your vehicle, make
sure that the plug and the cord
on your electrical appliance will
not interfere with your shifting
gears and operating the accel-
erator and brake pedals. If they do, do not use the electrical
appliance while driving.
& Use with a cigarette lighter (if
equipped) To use the accessory power outlet as a
cigarette lighter socket, purchase the
cigarette lighter plug, which is an optional
accessory. A cigarette lighter plug is
available from your SUBARU dealer.
The cigarette lighter operates only when
the ignition switch is in the “ ON ” or “ ACC ”
position.
To use the cigarette lighter, push in the
knob and wait a few moments. It will
automatically spring up when ready for
use.
WARNING
To avoid being burned, never grasp
the lighter by the end with the
heating element. Doing so could
result in injury and could also
damage the heating element.
CAUTION
. Do not hold the lighter pushed in,
because it will overheat. . The electrical power socket is
originally designed to use a gen-
uine SUBARU cigarette lighter
plug. Do not use a non-genuine
cigarette lighter plug in the sock-
et. Doing so may cause a short-
circuit and overheating, resulting
in a fire.
. If the socket is ever used for a
plug-in accessory such as a cell
phone, that may damage the
portion of the socket ’ s internal
mechanism that causes a cigar-
ette lighter plug to “ pop out ”
after its lighter element is heated.
Therefore, do not place a cigar-
ette lighter plug in a socket that
has been used, even once, to
power a plug-in accessory. Doing
so may cause the plug to stick
and overheat, creating a potential
fire hazard.Interior equipment/Accessory power outlets

as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ ride ” (over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle. Driver ’ s Control Center Dif-
ferential (C.DIFF/DCCD) (STI) WARNINGAlways use the utmost care when
driving. Being overconfident be-
cause you are driving a vehicle with
a driver ’ s control center differential
could easily lead to a serious acci-
dent.
CAUTION
. All the indicators will flash in the
event that the driver ’ s control
center differential has a malfunc- tion. Have the vehicle inspected
by your SUBARU dealer.
. If a malfunction occurs in the
vehicle (for example, when the
rear differential oil temperature
warning light illuminates), all of
the indicators may disappear and
the setting value for the initial
limited slip differential (LSD) tor-
que of the driver ’ s control center
differential (C.DIFF/DCCD) may
be cancelled. However, it does
not indicate a malfunction of the
C.DIFF/DCCD itself.
The driver ’ s control center differential
allows you to freely change the degree
of limitation of the differential action
(limited slip differential (LSD) torque) of
your vehicle ’ s center differential.
By using the center differential control
switch, you can set an initial LSD torque to
match the road surface conditions, driving
conditions and your driving style.Starting and operating/Driver ’ s Control Center Differential (C.DIFF/DCCD) (STI)

– When a temporary spare tire
is installed
– When your vehicle is towed
– When the vehicle is stopped
with the manual mode se-
lected
NOTE . A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck
in snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
. The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the “ LOCK ” / “ OFF ” position. How-
ever, the initial LSD torque will be
minimized when the battery is discon-
nected and reconnected.
. During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may cause a braking effect accompanied by
vibration and noise. This does not
indicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem.
. Use the center differential indicator
only as a rough indication of the initial
LSD torque.
. If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem.
& Temporary release When the driver stops the vehicle and
pulls the parking brake lever after manu-
ally setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver ’ s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored. Continuously variable trans-
mission The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNINGDo not shift from the “ P ” or “ N ”
position into the “ D ” or “ R ” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION. Shift into the “ P ” or “ R ” position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more
than 5 seconds in any position
except the “ N ” or “ P ” position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
. Never move the vehicle rearwardStarting and operating/Continuously variable transmission

mode, the SI-DRIVE mode will stay in
the same mode as when the engine
was turned off.
. While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.
. If any of the SI-DRIVE indicators
blink, the SI-DRIVE system may be
malfunctioning. Contact your SUBARU
dealer.
. While the engine is cool, you cannot
change to Sport Sharp (S#) mode. SI-DRIVE (except STI: CVT
models) SI-DRIVE (SUBARU Intelligent Drive)
works to maximize engine performance,
control and efficiency.
This system consists of three modes:
Intelligent (I), Sport (S), and Sport Sharp
(S#). By operating the SI-DRIVE switches,
the character of the power unit changes.
& Intelligent (I) mode ! For smooth, efficient performance
driving
The linear acceleration characteristic of
the Intelligent (I) mode is ideal for normal
driving usage. The Intelligent (I) mode provides well-
balanced performance with greater fuel
efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency.
This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttle
response.
& Sport (S) mode ! For all-around performance driving
The Sport (S) mode provides the engine
power desired by those who want to make
the driving experience their own personal
adventure.Starting and operating/SI – DRIVE (except STI: CVT models)

other than Sport Sharp (S#) mode is
selected.
NOTE . The next time you turn on the
engine, after you turned off the engine
in the Sport Sharp (S#) mode, the SI-
DRIVE mode changes to the Sport (S)
mode.
. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in
the same mode as when the engine
was turned off.
. While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to another mode.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.
. While the engine is cool, you cannot
change to Sport Sharp (S#) mode. Limited slip differential (LSD)
(STI) The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD. Power steering & STI The vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTIONDo not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.Starting and operating/Limited slip differential (LSD) (STI)

& Except STI
Power steering warning light
The vehicle is equipped with an electric
power steering system. The power steer-
ing system operates only while the engine
is running. When the ignition switch is
turned to the “ ON ” position, the power
steering warning light on the combination
meter illuminates to inform the driver that
the warning system is functioning properly.
Then, if the engine started, the warning
light turns off to inform the driver that the
steering power assist is operational.
CAUTION
While the power steering warning
light is illuminated, there may be
more resistance when the steering wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
NOTE If the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
